In the open waterway, it is still impossible to isolate foreign fouling substances.

In addition, chemical additives can also be used to change the characteristics of the fouling substance and reduce the generation of scale. Although this method is most widely used, the limited operating conditions cannot reflect the conditions of the external environment in time, and it is impossible to stably control, and in order to strengthen the additive. The effect is to reduce the concentration ratio, increase the amount of replenished water, increase the discharged sewage, and easily increase the water consumption, increase the environmental pollution, and increase the treatment cost of additional sewage.
